      blk-mq: make per-sw-queue bio merge as default .bio_merge · 9bddeb2a
      Ming Lei authored
      Because what the per-sw-queue bio merge does is basically same with
      scheduler's .bio_merge(), this patch makes per-sw-queue bio merge
      as the default .bio_merge if no scheduler is used or io scheduler
      doesn't provide .bio_merge().

      blk-mq: merge bio into sw queue before plugging · ab42f35d
      Ming Lei authored
      Before blk-mq is introduced, I/O is merged to elevator
      before being putted into plug queue, but blk-mq changed the
      order and makes merging to sw queue basically impossible.
      Then it is observed that throughput of sequential I/O is degraded
      about 10%~20% on virtio-blk in the test[1] if mq-deadline isn't used.
      This patch moves the bio merging per sw queue before plugging,
      like what blk_queue_bio() does, and the performance regression is
      fixed under this situation.
      [1]. test script:
      sudo fio --direct=1 --size=128G --bsrange=4k-4k --runtime=40 --numjobs=16 --ioengine=libaio --iodepth=64 --group_reporting=1 --filename=/dev/vdb --name=virtio_blk-test-$RW --rw=$RW --output-format=json

      blk-mq: Only register debugfs attributes for blk-mq queues · a8ecdd71

      The code in blk-mq-debugfs.c assumes that it is working on a blk-mq

      register blk-mq debugfs attributes for blk-mq queues.

      Currently only the PCIe driver supports metadata, so we should not claim
      integrity support for the other drivers.  This prevents nasty crashes
      with targets that advertise metadata support on fabrics.
      Also use the opportunity to factor out some code into a separate helper
      that isn't even compiled if CONFIG_BLK_DEV_INTEGRITY is disabled.
